Dark Matter & LZ Experiment
-Dark Matter: Invisible matter that does not emit or reflect light; inferred mainly through its gravitational effects on visible matter.
-Fritz Zwicky (1933): First proposed the concept of “missing mass” while studying the motion of galaxies in a galaxy cluster.
-Evidence: Galaxy rotation, gravitational lensing and formation/distribution of large-scale cosmic structures support the existence of dark matter.
-Cosmic composition: Ordinary (baryonic) matter constitutes only about 5% of the universe; dark matter about 27%.
-WIMPs (Weakly Interacting Massive Particles): One of the major hypothetical candidates for dark matter; not yet conclusively detected.
-LUX-ZEPLIN (LZ): Dark-matter experiment located at the Sanford Underground Research Facility, South Dakota, USA.
-Recent finding: LZ researchers reported a single WIMP-like event, but it does not constitute confirmed detection of dark matter.

Nuclear Energy Expansion: Key Challenges and Way Forward
Context: India aims to expand nuclear power capacity from around 8 GW to 100 GW by 2047, requiring nearly ₹20–22 lakh crore investment.
Key Challenges
-Fuel Security: Limited domestic uranium and enrichment capacity creates dependence on imported uranium/LEU, exposing the sector to geopolitical and supply-chain risks.
-High Capital Cost: Nuclear plants cost around ₹15–20 crore/MW, substantially higher than conventional power projects.
-Long Gestation: Projects may take 8–10 years before revenue generation, increasing interest during construction and overall project cost.
-Financing Gap: Financing may constitute 30–50% of levelised nuclear electricity cost; conventional bank finance is unsuitable for such long-duration projects.
-Risk & Liability: Safety, radioactive-waste management, construction delays and liability allocation can discourage private and foreign investment.
-Technology Dependence: Scaling capacity requires reliable reactor technology, equipment supply chains and domestic manufacturing capabilities.
Way Forward
-Secure the nuclear fuel cycle: Long-term fuel contracts, diversified suppliers and development of domestic enrichment/fuel-cycle capabilities.
-Mobilise patient capital: Pension/provident funds, insurance funds and institutional investors suited to long-duration infrastructure.
-Innovative finance: Sovereign/partial credit guarantees, infrastructure bonds, InvIT-type structures, low-cost long-tenor loans and post-commissioning refinancing.
-Better risk allocation: Government should absorb policy/regulatory risks while developers bear controllable construction and operational risks.
-Domestic ecosystem: Strengthen indigenous reactor technology, component manufacturing, skilled manpower and nuclear waste-management infrastructure.
-Regulatory certainty: Predictable approvals and an enabling liability framework can crowd-in private investment without compromising nuclear safety.
Conclusion: Achieving 100 GW nuclear capacity requires moving beyond a reactor-centric approach towards an integrated ecosystem of fuel security, patient finance, indigenous technology, credible regulation and effective risk-sharing.

Bihar plans phase-wise plantation of toddy palm (Palmyra) trees across districts as a natural lightning-protection measure; palms are good electrical conductors that can channel lightning electricity to the ground, reducing deaths, especially in rural areas.

-Municipal Grants: Bihar Cabinet approved Rs. 9,169 crore as basic and performance grants to all municipal bodies for 2026–27 to 2030–31, as recommended by the 16th Finance Commission; distribution in 90:10 ratio - population : own-source revenue.
-Mukhyamantri Samagra Shahri Vikas Yojana: Tenure extended by 5 years up to 2030–31; covers roads, drainage, parking, footpaths, street lighting, lakes, parks, ghats and water bodies; Rs. 5,500 crore outlay, implemented by BUDCO.
-Urban Grants – Performance Link: 10% of funds will be linked to performance of urban local bodies, while 90% will continue to be population-based.
-Saat Nischay-3: Bihar approved formation of the Bihar State Goat Rearers Cooperative Federation under Saat Nischay-3, with an estimated outlay of Rs. 14.80 crore over 3 years.

Technology as a Double-Edged Sword
-Prosperity vs Livelihood: Industrial Revolution multiplied production but displaced artisans and traditional industries, especially Indian textiles.
-Efficiency vs Employment: Gandhi warned against the “craze” for labour-saving machines in a society where millions needed work- a concern renewed by AI and robotics.
-Wealth Creation vs Concentration: Technology creates enormous wealth, but without fair distribution it can concentrate economic power in a few hands.
-AI is the new industrial dilemma: AI can raise productivity and reduce drudgery, but can also replace both physical and cognitive labour, widening inequality.
Takeaway: “The question is not whether technology advances, but whether humanity advances with it.”
